From this interview in The Atlantic with Jeffrey Goldberg:

JG: A final question: Senator Obama talked about how his life was influenced by Jewish writers, Philip Roth, Leon Uris. How about you?

JM: There’s Elie Wiesel, and Victor Frankl. I think about Frankl all the time. “Man’s Search for Meaning” is one of the most profound things I’ve ever read in my life. And maybe on a little lighter note, “War and Remembrance” and “Winds of War” are my two absolute favorite books. I can tell you that one of my life’s ambitions is to meet Herman Wouk. “War and Remembrance” for me, it’s the whole thing.
Then there’s Joe Lieberman, who lives a life of his religion, and who does it in the most humble way.
JG: Not a big Philip Roth fan?
JM: No, I’m not. Leon Uris I enjoyed. Victor Frankl, that’s important. I read it before my captivity. It made me feel a lot less sorry for myself, my friend. A fundamental difference between my experience and the Holocaust was that the Vietnamese didn’t want us to die. They viewed us as a very valuable asset at the bargaining table. It was the opposite in the Holocaust, because they wanted to exterminate you. Sometimes when I felt sorry for myself, which was very frequently, I thought, “This is nothing compared to what Victor Frankl experienced.”

I didn’t know that Hermann Wouk was Jewish.
